Citizen Spare Part 393-4013 / 650-603 (1 Piece) – Oval Glass/Cushion Gasket (Cushion Packing, maintenance-free) – NOS

Original Citizen Glass/Cushion Gasket with reference 393‑4013 (corresponds to Citizen reference 650‑603) from new old stock (NOS). Offered is a single piece, taken from an original Citizen package (純正部品 / "5 PCS"). On the original label, the part is designated as "パッキング" (Packing/Gasket); technically, it is an oval cushion/glass gasket.

Dimensions: approx. 0.85 mm (thickness) × 30.15 mm × 32.45 mm – the different axis dimensions confirm the oval shape, suitable for the corresponding Citizen glass (風防) reference 2026. According to the original specification, the gasket ring is maintenance-free and does not require oiling (注油不要 / "no oiling required").

The gasket seals the glass against the case and is essential for restoring the original water resistance of classic Citizen watches.

The part is unused and ideal for professional overhaul, where suitable original gaskets are now difficult to obtain.

Manufacturer: Citizen Watch Co., Ltd. (純正部品 / Japan).

Warranty (used) This is an original part (NOS) stored for decades. The limitation period for claims for defects (statutory warranty) is 12 months from delivery.

Note As this is an old stock gasket, the material may lose elasticity or become brittle due to age. Therefore, a guarantee of water resistance is not possible; the gasket should be checked before installation and only installed professionally.
